Claims. 1

My invention relates to improvements in typographical casting machine stops, and particularly to a safety device for application to and use upon Linotype and Intertype and like typographical composing and line casting machines.

An object of this invention is to provide an attachment for Linotype and other type casting machines which is designed to prevent a line casting machine from sending an assembled line of matrices into the machine when the line is either too long or too short.

A further object is to provide an automatic stop in the nature of an assembling elevator lock which will prevent sending in long or tight lines as well as short or loose lines of matricesas these are assembled for movement to casting positions, so that the thus improperly assembled line will not be sent into the machine for castmg.

Another object is to provide stop means automatically operating as the matrices are assembled so that if the assembled line is too short or too long the machine stops before the line of m trices of improper length is elevated to the po tion from which it goes to the casting -mechanism, so that possible damage to the matrices assembled space bands or other damage such as spurting of metal will be avoided.

Still another object is to so construct and arange the parts that the stop mechanism and the operating means therefor can be quickly and readily embodied in connection with standard parts of such machines, and without material structural alterations.

Yet another purpose is to provide stop means having the parts thereof actuated by normal functional operations of the machine, and which stop means will consequently be substantially automatic in its operation and functioning.

Another object is to provide stop means that can be fitted upon and can be mounted in con.- nection with the usual parts of amachine, and which provides for adjustment and setting of the parts so that the machine can be operated in usual normal manner, and without actuation of the automatic stop. a

With the above and other objects in View, some of which will be apparent to those skilled in the art, and others of which are inherent-in the use and operation of my improved structure, this Fig. 2 is a view in perspective showing an assembler slide roll bracket with the main portions of this invention applied thereto.

The disclosure in Figure l of the drawings is intended to represent only fragmentary portions of a typographical casting machine, such as the fLinotype or"Interty-pe machines, and the portion thus illustrated. discloses the assembling elevator and assembler slide and the assembler slide roll bracket of an ordinary machine, with which parts :my present invention is particularly concerned.

The assembling elevator is adapted to receive the matrices and space bands, and to elevate these to other portions of the machine where they areheld in position to receive molten metal from which a slug or line of type is cast. This assembling elevator is generally indicated at l, in Figural of the drawing, and the assembler slide roll bracket is indicated at 2, the roll thereof be.- ing shown at 3. An assembler slide ,4 is mounted for substantially horizontal movement within the machine, in the usual manner. In fact, the parts of the machine as particularly described, and all other parts and operating features, can be of substantially standard form and construction in their general shape.

The parts of my invention are assembled upon and cooperate with the assembler slide roll bracket ,2 and the assembler slidelii, and the stop structure to be hereinafter more fully described is intendedand adapted to prevent movement of the ass em blingnelevator if a line of assembled matrifiQS and space bandsas supplied thereto be t o short .0 7 t clon n othe Words. th device stops the too long or too short assembled line in the machine where no damage can result to either the matrices or the space bands.

The assembler slide roll bracket 2 is cut away or reduced on its rear sideas at 5, as best shown in Figs. 3 and '4, and a lock lever 6 is pivotally mounted on a shoulder screw I, or other suitable pivoting means so that this lever will be freely swingable. The lower end of the lever is provided with a locking lug 8, and is preferably cut away or otherwise made sufficiently light that the upper end 9 of the lever will overbalance and will consequently swing the lower end of the lever to move the locking lug 8 to project beyond the side of the assembler slide roll bracket 2, and a stop is provided at H to limit the projection of the locking lug end 8.

The stop it normally limits outward swinging movement of the lower end of the lever B, and an eccentric cam H is rotatably mounted on the rear side of the assembler slide roll bracket 2 and is adapted to be turned through the medium of operating lever I? on the forward side of the bracket, and consequently readily available to the machine operator, to interpose the cam to limit swinging movement of the lower end of the lever il so that the locking lug end 8 will not project beyond the side of the assembler slide roll bracket 2. This eccentric cam H is provided to permit adjustment and setting of the parts so that the locking end 8 of the lever B will be held in a position where it will be ineffective to lock or stop movement of any part, and the eccentric cam H and setting lever [2 are provided to permit the operator to render this stop means inoperative, so that the machine can be operated in usual manner, when desired.

At its upper end 9, the lever B is offset so that it will be substantially aligned with the roll 3, and consequently the assembler slide 4, and this offset end is freely swingable below and immediately adjacent to the lower edge of the assembler slide 4. The end 9 of lever B has a screwthreaded opening therethrough, and acontact member l3, in the form of an elongated screw, is fitted through the opening with the end l4 thereof projecting as an adjustable contact portion.

The assembler slide 4 is cut away or otherwise reduced on its rear side to provide a recess 15, which extends longitudinally of the elongated assembler slide bar in that portion above the swinging end of the lever 6, and the assembler slide has a plurality of openings l6 bored or otherwise formed therein and extending substantially transversely of the bar from the lower edge, these openings being substantially in communication with the recess l5. An operating lug I! has. pins 18 thereon adapted to be fitted through openings It in the assembler slide 4 to depend from the lower edge of the assembler slide in substantially the manner shown in Figs. jl and 8. A detent spring I8 is provided within the recess 15 to engage with the pins l8 and thus retain the detachable lug ll in position. This spring l9 can hold the pins l8 through frictional engagement, or slight tooth formations can be provided on the pins, as indicated at 20 in Fig. 9.

When the detachable lug I I is fitted in position upon the assembler slide 4, and this slide is moved endwise, and to the left as the parts are shown in Fig. 1, the contact end ll of the screw I3 carried by the upper end 9 of lever B will be engaged by the end face of the lug and in consequence the lever B will be swung sufliciently to swing the lower end of the lever and withdraw the locking lug 8 from its extended position.

The assembling elevator is provided with a projectionll, shown in Fig. 1, which is engaged by 1 the stop lug 8 when this lug is in the extended position, and consequently when the lever 6 is 4 swung to a position to withdraw the stop lug 8, the assembling elevator can be moved upwardly. The detachable lug H can be adjusted by placing the pins l8 thereof in different openings It as formed in the lower edge of the assembler slide 4, to thus accomplish settings of the'stop parts for lines of different lengths, and the screw 63 can be turned to adjust the length of extension of the contact end l4 for more minute adjustments.

If too few matrices are assembled in one line,

. and if the line of assembled matrices and space bands is consequently too short or too loose, the assembler slide t will not go far enough to bring lug ll into engagement with the contact end M and consequently the lever 5 will not be swung sufficiently to withdraw the stop or looking lug 8 of the lower end of the lever from a position where it will permit passage of the projection or shoulder 2 l If the line be of proper length, or too long, the lug ll will engage contact i l and the lever B will be swung to withdraw the locking lug end 3 to permit movement of the assembling elevator to advance the assembled line of matrices and space bands to the casting position.

The above described parts will provide an automatic stop to prevent advancing a line that is too short or too loose; but, my invention also contemplates employment of these same parts to prevent the advancing of an assembled line of matrices and space bands that is too long or too tight. Where the assembled line is too long, the lug ll engages the contact l4 and swings the lever 6 to move the lower end thereof a distance somewhat greater than is necessary to merely withdraw the stop or looking lug end 8 to the position where it will clear the projection or shoulder 21, and I employ this greater movement of the lower end of the lever to actuate a second step means.

This second stop means is adapted to interpose a stop that will prevent movement of the assembling elevator to advance an assembled line that is too long or too tight. A supporting bracket 22 is mounted upon and extends laterally from the edge of the lower portion of the assembler slide roll bracket substantially below the position of the lever 6, and this bracket has a slide 23 thereon positioned to be engaged by the lower end of the lever 6 upon the increased or greater swinging movement of this lever, as just above described. A lever 24 is swingably mounted by a pin or other suitable pivoting means, upon the bracket 22 with one end thereof engaging the outer end of the slide 23, and a spring 25 is provided to normally exert resilient force to draw the contacting end against the slide and consequently move the slide to its innermost position. The assembler slide roll bracket 2 has an opening 26 bored or otherwise formed substantially obliquely therethrough, as best shown in Fig. 5, so that a locking bolt member 2! can be slidably mounted through this opening with its bolt end substantially in a position to be extended to engage the projection or shoulder 2| of the assembling elevator. The belt member 2'! is extended at its inner end and is pivotally connected with the swinging end of the lever 24, as at 28.

With the second stop mechanism as described, movement of the assembler slide 4 in a relation to advance a lone. or tight assembled line of matrices and space bands will cause the lug H to swing leverB to bring the lower end thereof into contactwith the slide 23, in consequence of which the lever 2E will be swung to actuate thereof into a position the path of the projection or shoulder 2! of the assembling elevator, and therefore this assembling elevator cannot be moved to advance the: long or tight line. To provide for adjustments of the parts, an ad j-usting screw 29 isprovided on the lever 24 its end ad j astabl y bearing against the slide 23'.

By removing the detachable lug. ii, the as.- sembl'er slide 4- is free: to movewithout afiecting in any way the lever 6, and consequently when the operator desires to release: or render inoperative the stop means, he will not only operate the handle W to interpose the eccentric cam- H to engage the lever 6 and withdraw the locking log 8 but will also remove this detachable lug 1?. When the automatic stop means. is thus rendered inoperative, the machine can be used the usual: manner.

To protect the. operating parts of the second stop means, a shield or cover 30', best illustratedin Figs 6 and '7, can be provided. This cover or shield is preferably removable so that access can: readily be had to the. parts, but it will be seen that the end of the cover or shield is open to permit access to be had to the adjusting screw 29 fior adjustments of the parts.

The screws ['3 and; 29 provide for adjustments to give. desired clearances for the two stops, and. it desired, nuts 3i and 31' can be provided on one: or both of these screws to hold or retain the adjustments thereof. As stated, since the assembler slide 4 has a plurality of sockets or openings Hi therein, the detachable lug. H can be adjusted to desired positions to accommodate difiierent lengths of lines to: be set by the machine.

From the foregoing it will be seen. that I have provided. stop means adapted for use with Linotype, Intertype or other line casting machines, which is of. simple and inexpensive construction, and which. will operate efficiently to stop the mechanism if the assembled matrices and space hands be either too long or tootight, or too short or too loose, and which will operate to prevent advancing of the long or short line to the casting position, thus protecting the machine and the parts before the assembled matrices have been advanced to a point where damage will. be likely tobe. done to the matrices andpossi-bl-y to the machine.

While I have herein shown and described only certain specific embodiments. of my invention and have suggested only certain possible modifications, .it will be apparent to those skilled in the art that many changes. and variations can be. made in the design and construction and assembly of. the parts, and in the manner of .operating and of rendering. the parts operative and inoperative, without departing from the spirit and scope of my invention as set forth in the appended claims.
